(d) all of the above

Explanation:

Cardiac muscle is a multinucleated muscle. Multinucleation is also termed as syncytium.
The neural mechanism responsible for generating impulse to help the heart work is also present in the heart. It is the sino atrial node (SAN) present in the right atrial wall. It sends impulses at regular intervals down the Purkinje fibres and the bundle of His. This the heart is rhythmic too.
